SPECIFICATION forming part of Letters Patent No. 629,810, dated August 11899.

Application filed April 13, 1898.

ply the outer sole to the lasted shoe and then 1 while the sole isheld-in place trim the same, giving to it the shape of the last, asuitable guide working usually in the space between the junction of thewelt and the upper while the surplus material of the sole is beingremoved from a point back of the shank-about the ball and toe, thusshaping the sole exactly in conformity to the shape of the last.Frequently the sole while being so trimmed or shaped is channeled. lheheel end of the sole, called the heel-seat, is not, however, trimmed toshape in this usualmachine for the reason that in the absenceof thewelt, which does not extend about the heel-seat,

the guide used would not find a proper bearin g, and consequently theheel-seat would not betrimmed correctly and has to be done at asubsequent operation.

I have devised a novel machine for trimming the heel-seat end of thesole, thus fully preparing the sole for the subsequent steps ofattaching the sole to the welt and applying the heel to the heel-seatend of the sole.

My novel machine has a pattern-plate, it in this instance of myinvention being represented as stationary, said pattern-plate being ofthe shape which it is desired to give to the heel-seat end of the sole.The heel-seat end sustained on this pattern-plate is acted upon by aclamp interposed between the upper and inner sole and the inner side ofthe outer sole the edge of which is to betrimmed, said clamp beingpreferably operated automatically to efiect the firm clamping of thestock in one movement of the" bladecarrier, to be describedthat is, thatpart of its stroke when the heel-seat is being trimmed-the clamppreferably rising immediately after the trimming or rounding has beenefiected and while the carrier and blade are being returned into SerialNo. 677,'52. (No modem their'nornial orstarting position. This clampwill preferably be provided atits under side with aprojection which mayapproximate in shape the shape of the pattern, such projecwhich is freeto slide in a guideway occupying a position substantially parallel witha line which would divide the sole from end to end, said block derivingits movement to and fro in said guideway by or through an arm pivotallymounted on or with relation to said block, said arm deriving its motionfrom a second arm which is moved to and fro in the arc of a circle, thetwo arms being shown as made movable about different centers and asbeing connected loosely one with the other by a pin-and-slot or.other'loose connection.

The lever upon which is mounted the carrier referred to is provided atone end with a suitable roller or other stud which enters an irregularcam-groove in a plate, preferably the same plate which is provided withthe guideway referred to, in which moves the slide-block carrying thelever hereinbefore mentioned. This plate will also have, preferably, asuitable groove to receive a projection of the pattern-plate on whichrests the end of the sole to be trimmed or rounded for the production ofthe heel-seat.

The carrier is so mounted on the lever referred to that it may slideback and forth under the control of a suitable spring or springs tothereby enable the carrier to adapt itself to difierent sizes ofpatterns according to the size of the shoe the heel-seat of which is tobe rounded.

Figure 1, in vertical section, shows a machine embodying myinvention inone form, said machine being partially broken out to save space on thedrawings. Fig. l is annuder side view of the clamp. Fig. 2 is a top viewthereof on a smaller scale. Fig. 2 is a right-hand end view of some ofthe parts shown in Fig. 2. Fig. 3 is a detail in top view, the pattern,clamp, and counter-guide being omitted; and Fig. 4: shows the bed-plateas transparent, with the devices underneath, chiefly in dotted lines,for moving one of the arms referred to for imparting motion to the leverhaving the blade-carrier.

The framework of the machine consists, essentially, of suitable legs A,having mounted upon them a top plate A, above which is supported insuitable manner a-bed-plate B, a standard B being erected on thebed-plate. The bed-plate has connected to it at one end, as by ascrew-b, a stand B on which rests a plate 0, said plate being held inposition by a suitable screw 0. This plate Chas (see Fig. 2) anirregular cam-groove c and it also has a guideway 0 (Shown in Figs. 1and 3 by full lines.) The opposite end of the plate C- issuitablysustained rigidly with relation to the stand B" and thebed-plate.

The stand B has a suitable guideway Z), preferably dovetailed incross-section, in which fits to slide a dovetailed projection Z2 of aclamp B the under side of said clamp being cut away, preferably, toleave a projection I), (seeFigs. 1 and 1,) the outlines of saidprojection approximatingin shape the end of the pattern D and when inoperative .position falling preferably with the'face of said projectioninside the edge of the pattern. The upper side of the clamp ispreferably tapered on the lines 0 so that the said clamp may be readilyinserted between the upper of the shoe (designated by dotted lines e)and the heel-seat end 6 of the sole of the shoe, said sole, it beingunderstood, being at such time secured in some way to the lasted shoe onthe last in order that the heel-seat end may be trimmed to the desiredshape-a shape determined by the pattern D. This pattern in this instanceof my invention has a suitable dovetailed or other shaped projection, asd, which enters a dovetailed groove (see Fig. 2) in the plate 0,preferably the same screw 0 hereinbefore described, acting, when turnedin fully, to clamp and retain the said patternplate in its workingposition.

The pattern-plates used will be of dilferent sizes, according to theparticular size of the heel-seat end which is to be trimmed, and onepattern-plate may be readily substituted for another one of the propersize, as desired.

The bed-plate B has a suitable hole for a short shaft 6 having appliedtoits lower end a pinion a which is engaged in this instance of myinvention by the teeth of a sector-lever e pivoted at 6 saidsector-lever being shown as slotted, as at a, said slot being entered bya crank 6 carried by a disk a fast on the upper end of a shaft 6provided, as represented, with a suitable beveled gear 6 which isengaged and rotated by a beveled gear 6 fast on a shaft 8 which derivesits motion from any usual or suitable automatic clutch, so that saidclutch controlled by a treadle in groove f, in which may enter a rolleror other stud f, extended from a rod f attached to an arm f fixed to arock-shaft f, mounted in the stand B, said rock-shaft having a sec- .ondarm f which is'suitably joined'to an ear of the clamp B The cam-groove freferred to is of such shape that when the machineis in its stoppedposition the said clamp will occupy its elevated position, the camimmediately after the machine is started acting to depress the clamp andholding it depressed substantially throughout the trimming or roundingoperation, at which time the cam will act to again effect the raising ofthe clamp to release the heal-seat end of the sole.

The shaft 6 has suitably connected to its upper end (see Fig. 1) an armg, herein represented as provided With a slot g, which is entered by apin or stud g of a second arm h, connected with a rocking stud 7L,extended through a block 72?, mounted to slide to and fro in theguideway 0 of the plate G hereinbefore described. The upper end of thisrocking stud It has suitably pinned to it a lever 72 provided at one endwith a roller or other stud 7L3, which enters the cam-groove c of theplate 0. This lever at its opposite end is slotted, as at 2, to receivea carriage 3, on which is pivoted at 4 a suitable carrier 5, havingat'its end next the pattern plate suitable rollers 7 to-contact with theedge of said pat.- tern-plate, said carrier having a groove in which isfixed in an adjustable manner by a suitable set-screw the shank of ablade 8 the blade used to round or trim the heel-seat end 6 of the sole.A suitable spring 10, located in the lever 7L2 and acting against aportion of the carriage 3, serves normally to keep the rolls of saidcarrier in contact with the edge of the pattern, the spring yieldingmore or less as the carrier mounted upon the lever is moved about thepattern in the trimming of the heel-seat end of the sole.

Figs. 2 and 3 show the carrier and its blade in their normal position,and while the carrier is being moved in the direction of the arrow Fig.23 around tothe point 13 (see Fig. 3) of the pattern the clamphereinbefore referred to will act to hold the heel-seat end of the solefirmly pressedagainst the pattern; but soon or immediately after thearrival of the blade in the position'l the said clamp may be raisedwhile the carrier is being returned into its normal position ready toagain act upon and trim and round another heel- ICC seat, and duringthis return movement of the carrier and blade the trimmed or roundedheel-seat is'withdrawn with the shoe from themachine.

When the shoe is being put into position to have the heel-seat end ofthe sole trimmed, the counter of said shoe or the upper at a pointsurrounding the usual counter is forced back into the counter-guide m,shown as composed of two bent spring-arms. Preferably the acting end ofthe clamp will be out out, leaving it of a forked or U shape, as in Fig.1.

Believing myself to be the first to devise a machine having a clamptoact upon the heelseat end of the sole after the sole is applied at itsfore part to a lasted boot or shoe to thereby clamp the said heel-seatend transversely and firmly upon a pattern-plate while the heel-seat endis being trimmed or rounded to shape, this invention is not limited tothe precise form or shape of clamp or to the exact means described foractuating said clamp, as it will be obvious to those skilled in the artthat the construction and shape of the clamp and its actuating'meansmight be variously modified with only the skill of the mechanic andWithout invention.

It will be noticed that the short shaft 6 and the short shaft h occupydifferent centers, and the provision of allowing the shaft h to move toand fro in the guideway While the lever upon which is mounted thecarrier and its blade is being moved about the pattern enables thecarrier and blade to follow correctly the pattern, which is not in thesame curved line, but is in varyinglines or contour, according to theshape to be given to the heel-seat end of the sole.

In this invention the clamp made the subject of this claim does not actagainst the edge of the sole at its heel-seat end, but said clampis soshaped that it may be interposed between the upper side of the sole asyet unattached to the upper at its heel-seat end, said clamp acting uponthe upper side of the sole next the lasted upper and clamping ittransversely against the face of the patternplate, leaving the edge ofthe outer sole to be rounded projecting between said clamp andpattern-plate, so that the blade, actuated by the carrier, may traverseabout and trim the heel-seat end while itis clamped transversely or inthe direction of the thickness of the sole between said clamp and thepattern-plate.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, ise 1.
